The quenching and tempering of metallic surfaces not only has aesthetic reasons, but also affects the longevity of the formed components. For this reason, the Colsman performance includes various quenching and tempering processes: Grinding, barrel finishing, anodizing, shot blasting, powder coating, painting, and polishing and e-polishing. Grinding and barrel finishing smooth metal surfaces, while anodizing and blasting produce resistant coatings. Polishing and e-polishing provide a mirror-like shine, and powder coating and painting create a protective layer on the metal surface. The choice of process always depends on the desired appearance, durability and type of metal.
